An Act relative to responsibly reducing emissions in the transportation sector

This bill requires Massachusetts state agencies to transition their medium- and heavy-duty truck fleets to zero-emission vehicles (specifically battery electric models). Starting July 1, 2025, all new purchases or leases for such vehicles must be zero-emission, with the entire fleet fully converted by June 30, 2035. Exceptions are allowed if battery electric trucks don’t meet operational needs or charging infrastructure can’t support them, but agencies must explain each exception annually. The bill also mandates yearly reports detailing fleet composition, vehicle specifications, and justification for non-zero-emission purchases.
